Cartography is the science of making maps. A cartographer is sometimes referred to as a mapping scientist. They use aerial photography and data surveys to analyze collect and assemble geographical information. Based on this information cartographers create charts pictures of geographical areas and maps that are meaningful.

Cartographers have been around for centuries but today many of them have subspecialties within the field of cartography. For example photogrammetrists create scaled maps based on aerial photos and mosaicists arrange photographs in sequences. Cartographers not only create new maps but they also revise old ones using mathematical formulas computerized drafting tools and other computer software.

In addition to creating and revising maps some cartographers study the most current mapmaking techniques. Modern cartography often makes use of geographic information science (GIS) and some cartographers are geographic information specialists who specialize in using computerized data that combines mapmaking and surveying. Cartographers may work on a number of projects such as city plans street atlases country and navigation maps and charts and weather maps.

A number of them work for the United States government where they work on making paper and digital maps. They also work on various geographic cartographic and remote sensing projects. Cartographers are able to produce images from digital information they receive from earth-orbiting satellite sensors. reports that cartographers in the U.S. earn annual salaries that range from approximately $50000 to $65000.
